What lie? The truth behind that one is pretty well known. Hell, I knew the lady responsible for booking acts at the Pan Am center and she refused to book them after that very issue had been brought up by the band on a tour.

The only reason why ridiculous thing was famously in the contract was because it was their canary in the coalmine. Because of the pyrotechnics and equipment they used in their shows they had a number of specs that had to be followed to the letter for safety and legal reasons. If they showed up to a venue and see that the brown M&Ms weren't acknowledged then they'd have grounds to cancel for fear that their specs weren't followed.
